Which one is input device _____________.
Which one is input device _____________.
The correct option is D All of the above
An input device is a
piece of computer hardware equipment used to provide
data and control signals to an information processing system such as a computer or information appliance.
DVD:-
DVDdrives are input devices, since they read data into
the computer. A DVD burner
would also be an I/O device, since it can both read and write data to discs.
DVD is a disc capable of storing large amounts of
data on one disc the size of a standard compact disc.
Trackball:-
A trackball is a pointing input device. It
consists of a ball held by a socket containing sensors to detect a rotation of
the ball about two axes. It is like an upside-down mouse with a ball that
sticks out. The user rolls the ball with the thumb, fingers or the palm of the
hand to move a cursor.
Digitizers:-
Digitizersconvert analog or physical input into
digital images. This
makes them related to both scanners and mice, although current digitizers serve completely different roles. Digitizers carry out important work in
computer-aided design, graphics design and engineering.
